Zac Efron took his gorgeous god-like body onto Conan last night and pimped out his new comedy, That Awkward Moment!

Lo and behold, the 26-year-old super stud was about to have a super awks moment of his very own!

Referencing a scene in the film where his character pops some Viagra and boner HIGHlarity ensues, Conan O'Brien asked Zefron about his REAL life experiences with the erection pill!

As it turns out, he "his friend" took some once, and it gave him a giant HORSE dong!!!!! OMG!!!!

Ch-ch-check it out the interview for yourself…AFTER THE JUMP!!!

Then it tired him out!! Wait, what did? All the sex, we presume? AH-Mazing!!

WOW!!! If one-fourth of a Viagra gave Zefron "his friend" a huge equine erection — ha, what kind of Budweiser commercial that would make –we wonder what a whole pill would do to him and his triple-pretty peen!

In case you were wondering, we would pay lots and lots money to find out, LOLz!!!
